Two new benzophenones (1 and 2), were isolated from the endohydric moss Polytrichum commune. Their structures were elucidated by spectroscopic methods including extensive 2 D NMR techniques. Compound 2 is the first example of benzophenone with a rare cyclopropylacetamide from the natural resources. Compounds 1 and 2 were screened their cytotoxicity against five cancer cell lines (HCT-116, A-549, MCF-7, HepG2, A-375,), and no cytotoxic activities were observed (IC₅₀ > 100 μM).
